J' ET CONDENSER.

Application led January 24, 1920, Serial No. 353,866. Renewed October 14, 1925.

This 'invention relates to jet condensers. More specifically it relates to jet condensers adapted to be employed on the discharge or exhaust side of a vapor actuated motor such 5 as a steam engine or turbine.

In practice jet condensers are provided with liquid-inlet openings of vsuch size and configuration as to pulverize or atomize the condensing liquid. In order satisfactorily to perform this atomizing or pulverizing function these openings have been comparatively small with the result that they become clogged at times and therefore interfere with the continuous and efficient operation of the condenser. One of the objects of the present invention is to provide an arrangement in which these openings may be made large, freeing them from the tendency to become clogged, but in which the desired atomization or pulverization of the condensless uncondensed vapor when it leaves the fluid extracted from the condenser. Ani.

other object of the present invention is to provide means for freeing the gaseous fluid from steam .or other condensible vapor before it leaves the condenser.

is hereinafter disclosed.

In the drawing I have illustrated what I now consider a preferred physical embodi- L ment of my invention.

with an inlet ope/riding A for the steam or other vapor to be condensed. The water or other condensing liquid enters through the pipe B `and is distributed in the annular space C whence it issues into the condensing chamber through orifices D of such size as will prevent clogging in the ordinary use of the device. .Preferably the orifices D are arranged around the interior wall W of the he jet condenser illustrated is providedv condensing chamber in a plurality Vof superimposed rows, as illustrated. Balile means .are provided for securing the desired atom- ,stream of water issuingfrom each row-of orifices is caused to converge towards the central portion of the condensation chamber.

In this way an atomized' or pulverized condensing liquid is obtained even though the orifices D are of` large diameter. In order f to facilitate cleaning of the last mentioned orifices the outer wall of the chamber C is preferably provided with hand holes provid- 1ng easy access to the orifices. It will be noted that the inner wall W of the condensving ychamber is removable and may be put in place without friction against the inner side of the outer wall of the condensing chamber. The condensingchamber discharges` into asecond and lower chamber from which the liquid is drawn olf at P by any suitable means such as a centrifugal or reciprocating pump not shown;

While a large portion of the steam or other vapor which enters at A is condensed 1n the condensing chamber uncondensed steam enters the lower chamber together with the water and air. In order to remove yor separate this vapor from the air or 4other non-condensible gas before the. latter is drawn from the condenser, I provide within the lower chamber, preferably at the upper part thereof, a pan-like container shown 1n' Other objects and advantages will appear as the invention -"p'art ofthe liquid under pressure in the the form of an annular trough Gr. A small chamber C Hows into the said container G through an opening H. An overflow opening I is provided for the trough G which opening serves notv only as a llquijd outlet for the trough but also as an opening through which the gaseous fluid in the lower chamber passes on its way to the gas outlet J. -The latter may have connectedthereto a dry air pump of the usual type. The

passage of the' last mentioned'l uid is u through the opening I over the thin lm of water in the trough G (along two different paths), thence 'out through the outlet J. In

passing over' the thin film of water a large portion, if notl all, of the condensible vapor is condensed and thereby removed from the gaseous fluid. Y

It will be noted that the opening I is well above the level of the liquid in the lower chamber of the condenser even though the liquid may rise due to slowing up of the suction pump or the formation of too hi h a vacuum at low loads. Obstruction of t e said openin I is thus avoided.

1. A jet condenser comprising in combination a condensing chamber provided with a plurality of inlet openings for the condensing liquid, and annular baille means against whlch the incoming liquid .impinges and is directed towards the center of the chamber and across the path of the steam to be condensed.

2. A jet condenser comprising in combination, a mixing chamber provided with liquid-inlet and steam-inlet openings, a second chamber into which said mixing chamber discharges, a pan-like container within said second chamber, and means for conducting gaseous fluid from the upper part of the said second chamber, over said container and out of the condenser.

3. A jet condenser comprising in combination, a mixing chamber provided with liquid-inlet and steam-inlet openings, bale means against which the incoming liquid impinges and is directed into contact with the steam to be condensed, a second chamber into which said mixing chamber discharges, a pan-like container within said second chamber,l and means for conductin ...gaseousfluid from the upper part of sai a plurality of relatively large liquid inlet l openings, means comprising a flange for defiecting and atomizing the streams which pass through said openings, and a pan surrounding the outlet of said chamber and over which the uncondensed gas must pass in its exit from the condenser.

5. A jet condenser comprising in combination an outer casing, a wall within said casing cooperating with the latter to form a conduit for condensing liquid, said wall also defining the mixing chamber of the condenser and provided with a plurality of openings to enable the liquid in the conduit to be discharged into the mixing chamber,

a second chamber into which said mixing o chamber discharges, a pan-like liquid container provided with an overflow located bctween said chambers over which the gaseous fluid from the second mentioned chamber is condensed, and means for conducting liquid from the conduit to the container.

Intestimony whereof I hereunto afiix my signature.
